how to limit the toc depth to 2 (css-based PDF)

[galanohan]

Hi I'm modifying the css so that only level 1 and 2 topics are displayed in the TOC.

I took a reference from here:https://www.oxygenxml.com/doc/versions/ ... tents.html
and modify it like this:
/* Hide sections below level 2. */
*[class ~= "map/topicref"][is-chapter] >
*[class ~= "map/topicref"][is-chapter] >
*[class ~= "map/topicref"]:not([is-chapter]) >
*[class ~= "map/topicref"] >
*[class ~= "map/topicref"] {
display: none;
}
It doesn't work.

And I also tried with the following generic css rules:

.toc-entry.toc-h1,
.toc-entry.toc-h2
{
display: block;
}
.toc-entry.toc-h3,
.toc-entry.toc-h4,
.toc-entry.toc-h5,
.toc-entry.toc-h6
{
display: none;
}
They don't work either.

By the way, in the publishing template, I have the following parameter specified: <parameter name="args.css.param.numbering" value="shallow"/>. Being shallow means to have only level 1 topic titles included in the TOC, but changing to "deep" doesn't make sense either, as it will include all nested topic titles in the TOC.

Any hint? Thanks!

Hi,

In order to have shallow numbering and in TOC be displayed level 1 and level 2, use this CSS rule which i have created using CSS debugging topic.
I was looking to the elements which need to be hide, level 3 and below and saw that the class on that element is "map/topicref".
The I was looking to the rule that styles the parent of that element and find *[class ~= "map/topicref"][is-chapter]:not([is-part]) > *[class ~= "map/topicref"]:not(is-chapter).
I combined this 2 element to create a rule which will display:none any element that is children of the parent element and contains topicref.

Code: Select all

*[class ~= "map/topicref"][is-chapter]:not([is-part]) > *[class ~= "map/topicref"]:not(is-chapter) >  *[class ~= "map/topicref"]{
    display: none;
}

Thanks Andrei, it doesn't work, was it because I didn't include these rules within @media print {} , or is it a must to claim the usage by specifying @media and print?

Hi,

Could you sent me your CSS customization file on our support email, support@oxygenxml.com ?
I will to try to debug it in order to see why the rule that I gave you is not working.
